Excel 2007 : can't find were to set excel security warning

[chista 88]

Hi all
Made a client contact list and made matching client information folders,then I hyperlinked them together,works quite well but everytime I hit the hyperlink I get this message:Microsoft security message do you want to proceed.Then it has the option yes or no.Ive checked all over the place and can't find where to turn this setting off or to let excel 2007 know that the address the hyperlink is set to is safe and not to inform me everytime I hit the hyperlink.
Hope I explained it correctly the computer is at work and I did this from memory.Thanks Chista.
Hi again guys and gals: 5/15/2009
Well I found a way to remove the pesky security warning pop up.
If anybody is having the same issue you can try this but make sure you read all the steps before you continue. Later Chista!
